“I know what Cristiano Ronaldo’s injury is about, I’m working on him,” the witch doctor told Ghanaian radio station Angel FM. “I am very serious about it. Last week, I went around looking for four dogs and I got them to be used in manufacturing a special spirit called ‘Kahwiri Kapam’.

“I said it four months ago that I will work on Cristiano Ronaldo and rule him out of the World Cup or at least prevent him from playing against Ghana and the best thing I can do is to keep him out though injury. This injury can never be cured by any medic, they can never see what is causing the injury because it is spiritual. Today, it is his knee, tomorrow it is thigh, next day it is something else.”

Ghana is due to play Portugal on June 26 in Brasilia, in what will be the team's final match of Group G, which also includes Germany and the USA.
